Do not let any unwholesome talk come out of your mouths, but only what is helpful for building others up according to their needs, that it may benefit those who listen.
(Ephesians 4:29 (NIV))

Our mouths get us into so much trouble!

Sadly, what comes out of our mouths starts somewhere else. Even if we are good at holding our tongue, what does that say about our thoughts and our heart? Our mouth is simply a conduit for what is inside. We either focus on the worldly and sinful nature, or we focus on the traits that are of God.

The acts of the flesh are obvious: sexual immorality, impurity and debauchery; idolatry and witchcraft; hatred, discord, jealousy, fits of rage, selfish ambition, dissensions, factions and envy; drunkenness, orgies, and the like. I warn you, as I did before, that those who live like this will not inherit the kingdom of God.
(Galatians 5:19-21 (NIV))

What do you strive to have inside of you? Are you filled with the sinful nature of the world, or do you long for the characteristics that we know as the fruit of the Spirit? Do you long for your life, your words and your actions to reflect these traits?

But the fruit of the Spirit is love, joy, peace, forbearance, kindness, goodness, faithfulness, gentleness and self-control. Against such things there is no law. Those who belong to Christ Jesus have crucified the flesh with its passions and desires. Since we live by the Spirit, let us keep in step with the Spirit. Let us not become conceited, provoking and envying each other.
(Galatians 5:22-26 (NIV))

If unwholesome talk comes out of your mouth, what does that say about what is inside of you?
